Application December 31, 1947, Serial No. 794,938

Claims. (Cl. 12325) This invention relates to new and useful improvements in carburetors and the primary object of the present invention is to provide an attachment for the carburetor of an internal combustion engine that will supply moisture to the carburetor thus reducing the fuel consumption, and eliminating the formation of carbon from the spark plugs regardless of the escape of oil into the cylinder head.

Another important object of the present invention is to provide a moisturizer for carburetors operatively connected to a vehicle radiator and engine and so designed as to retain the engines water system cool, the radiator from steaming, the valves from burning out, and generally, which will efiect a more eificiently and economically operated engine than was heretofore available.

A further object of the present invention is to provide a moisturizer for carburetors that is extremely small and compact in structure and which may be quickly and readily applied to or removed from a carburetor in a convenient manner.

A still further aim of the present invention is to provide a moisturizer for carburetors that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure 1 is a fragmentary side elevational view of a vehicle engine, and showing the present invention applied thereto;

Figure 2 is an enlarged longitudinal vertical sectional view of the present invention and showing the air and vapor tubes broken away and shown in section; and,

Figure 3 is a transverse horizontal sectional view taken substantially on the plane of section line 33 of Figure 2.

Referring now to the drawing in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral I 0 represents a vehicle engine or internal combustion engine generally, comprising a radiator I2, a radiator fan I4, and a carburetor I6. The present invention does not attempt to claim the above conventional structure, but is merely an attachment to be used in conjunction 2 with the same to supply a moisture to the carburetor and thus increase the efiiciency of the engine and reduce the normal fuel necessary for the operation of the engine.

To accomplish the desired results, there is pro- I vided a hollow, cylindrical mixing chamber or body I8 ;having an open upper end 20. Frictionally embracing the upper open end of the mixing chamber I8, is the annular channeled end portion 22 of a concavo-convexed closure 24 which is provided with a pair of nipples 26 and 28, one of which for example nipple 26, projects outwardly from the channeled end portion 22, and the other of which, namely nipple 28, is arcuately formed and projects outwardly from the closure 24 adjacent the central portion thereof.

Rigidly secured to the inner periphery of the mixing chamber I8, is a plurality of inclined radial arms 30 that support a bearing plate 32.

20 Frictionally mounted in the bearing plate 32, is

the lower end 34 of a shaft 36, the upper end 38 of which frictionally engages a bearing block 40 fixedly carried by the inner face of the closure 24. Rotatably positioned on the shaft 36 for rotation between the plate 32 and a stop collar 42 fixed on the shaft 36, is the central portion 43 of a fan which is designated generally by the numeral 44. This fan 44 comprises a plurality of circumferentially spaced blades 46 so arranged as to direct a flow of air or vapor from the nipples 26 and 28 to the discharge nipple or conduit 48 that extends from the lower Wall 50 of the mixing chamber I8, and which engages the intake sleeve 52 carried by the carburetor I6.

Connecting the nipple 28 to the upper portion of the radiator I2, adjacent the overflow tubing 54 for the radiator I2, is a suitable vapor supply conduit or tube 56. Removably secured by any suitable means on the tubular extension 5! of nipple 26, is the reduced end of a funnel 58 having a screened major end 60 that is disposed adjacent the radiator fan I4 to receive air from said fan I4.

In practical use of the device, when the engine I0 is activated, the suction effected in the engine and hence the carburetor will cause the fan 44 to rotate thus drawing or sucking vapor from the radiator I2 into the conduit'56 and air into the extension 51, which vapor and air will enter the chamber I8 to be mixed or sucked into the carburetor I6. By mixing the vapor and air and conducting the same to the carburetor I6, the fuel in the carburetor will be diluted with the air vapor mixture to reduce the normal quantity of fuel necessary for efiicient operation of the engine.
